WIRE-NAIL MACHINE.

BPECIFICATION forming part oi Letters Patent No.345,745.1@d July 20.1856.

A pplicaiion filed January 5, 18556. Serial No. 187,662. (No model.)

.To @ZZ whom it may concern:

Be it known that I, MAX GUsrAv Voler, Sr., a resident of New York city,in the county and State ofNew York, have invented an Improved Wire-NailMachine, of which the following is a full, clear, and exact description,reference being made tothe accompanying drawings, in which@ Figure 1represents a side view of my improved wire-nail machine. Fig. 2 is anenlarged back view of the perforated ledge through which the wire passeson its way to th eheaders. Fig. 3 is a face View of that ledge and itsappurtenances. Fig. 4 is a top View of the saine, partly in section.Fig. 5 is a cross-section of the same on the line c c, Fig. 2; and Fig.6, a cross-section on the line k k, Fig. 2.

This invention relates to certain improvego ments on the wire-nailmachine which is described in Letters Patent No. 319,150, that weregranted to me June 2, 1885.

The invention consists in certain new means for adjusting the parts thatare carried by the perforated wire-guiding ledge, as hereinafter morefully described.

In the drawings, the letter A represents the frame of the machine; B,the driving'shaft; C, the reciprocating carriage, carrying the header D,and E E the levers for moving the horizontal slides F F. All these partsheretofore namedto wit, A B G D E F-are substantially like the partsbearing the same letters of reference that are described in theabovementioned Letters Patent.

The slides F F carry at their inner ends the cutters G G, and aredovetailed in a block, H, which is secured to the ri gidl y-proj ectingled ge I of the frame A. One part ofthe present in- 4@ Vention hasreference to the manner of securing this block II to the ledge I, withthe object of adjusting it thereon.

In order to make a heavier head on a nail, it is necessary that agreater length of wire be eX- posed to the heading-tools than isnecessary for producingaliead of less thickness. To accomplish thisadjustment, which is a backward and forward adjustment of the block H onthe face of the ledge I, I connect said block H with the 5o ledge by ascrew, a, (see Fig. 5,) the head of the screw resting in the block H,while the body of the screw projects outwardly on the back of the ledgeI, where it carries a toothed wheel, and a thumb-nut, d. This thumbnutholds the toothed wheel in position, as clearly shown in Fig. 5, andalso holds the block II'against the i'ront of the ledge at the requisitedistance. The block II at its back# that is, at that side which is incontact with the ledge I-has two upright ribs, c c, which 6o enterupright grooves in the front or face of the ledge I, and which, althoughpermitting up and down and back and forward adjustment of the block II,prevent lateral displace` ment thereof.

For the purpose of steadying the block II in its proper position, sothat the process of heading the nail may be carried on withoutdisturbance of the parts, I cause three or more screws, f f j", all ofwhich pass through the ledge I, to bear against the upright ribs c. Eachof these screws at its rear end carries a toothed wheel, g, which gearsinto the toothed wheel b on the screw a, so that on turning the saidwheel b the screws fff next to it will 75 be simultaneously adjusted tothe same extent as the screw a, that carries such wheel b.

It will be seen from theforegoing descrip tion that whenever the blockHis to be set nearer to or farther away from the face of the ledge I,for the purpose of giving less or more material for the head of the nailto be formed, it will only be necessary to loosen the two thumb-nuts d,and then turn the two wheels b Z1 so as to draw the blocks H toward theledge or move them farther off the ledge, as may be desired, the screwsf following the receding ribs e of the said blocks or moving away fromthem, as the case may be, so as to always maintain the proper contacttherewith, constituting, therefore, self adjusting rests for saidblocks, against which they will bear after the adjustment shall havebeen perfected.

The second feature of my invention has reference to the means of holdingin place on the machine the upper jaw, M, and the lower jaw, L, both ofwhich jaws are described by the same letters of reference in myabove-men' tioned patent. It becomes desirable from time to time toremove these jaws M L and have them replaced by others, according to thethickness of wire to be held by them.

ICO

The machine constructed according to the drawings annexed to my formerpatent required all the parts connected with the ledge I to be separatedor taken asunder before the jaws M L could be removed. My presentinvention seeks to obviate that difficulty, and provides a guide andsteadying-piece for the upper jaw, which, when taken olf the ledge,permits ofthe ready removal of said jaw, mal;- ing room, when it istaken out, for the removal also of the lower jaw, L. To aecomplish thispurpose I place a dovetailed plate, 71, over the center of the ledge I,and hold this plate on the ledge by Va screw, The plate 71 is dovetailedinto the space formed by and between the covering-plates m m, that areou the end portions of the ledge I, andthat carry the screws a a, bywhich the blocks H H receive their vertical adjustment. The dovetailedplate li, which, as stated, covers the ccn ter of the ledge I, isnecessarily also directly above the jaws M L, (see Fig. 6,) and abovesaid jaw M it carries a screw, j, by means of which the positionvertically of the jaw M cau be regulated. A faceplate, 0, is screwed tothe face of the ledge I over the recess occupied by the jaw M, andassists in holding said jaw in place, preventing it from failingforward. A set-screw, p, in the face-plate o clamps the jaw M at theproper height-that is to say, after the screw j has regulated the properheight for the jaw M the latter is clamped tight by the screw p. Byloosening the screw the plate h can be withdrawn, and thereupon, byloosening the screw p, the jaw M can be pulled out through the openingleft above it by the removal of h, and after that the jaw L can also belifted out through the same opening; hence the jaws L and M can beremoved and replaced for repair or other wise without disturbing anyother parts of the iVitncsses:
